Dynamic HTML and Java

Dynamic HTML – 2 aspects

•Interaction with user (could be forms or Javascript)

•Setting object properties dynamically (eg stylesheets)

Dynamic HTML (1)

•The essential aspect of Dynamic HTML is that the user is involved in providing input - usually via a form.

•The input is associated with variables - which should have a meaningful name (for example, v_shoes, v_coat).

•The variables are processed, usually by a set of JavaScript functions.

•Output is then made to the user - either by setting the values of fields in the table, or (as in the case of the example provided), by setting up a new window.

Java

• Java code is compiled to a .class file in an intermediate code (bytecode)

• This is downloaded and run on the browser by using the Java Runtime Environment (JRE) as a helper.

• Here’s an example• A useful site: www.javaboutique.com
